ELECTRIC HEATIN G AND LIGHTING APPARATUS.

Specification of Letters Patent.

Patented July 22, 1919.

Application filed April 24, 1918. Serial No. 230,603.

To all whom it may concern. I

Be it known that we, RICHARD G. LEDIG and ROBERT C. LEDIG, both citizens of the United States, residing in the city and county of Philadelphia, State of Pennsyl- Vania, and NIKoLAUs GERSON, a subject of the Emperor of Austria, having resided in the United States one year last past and having declared my intention of becoming a citizen thereof, residing in the city and county of Philadelphia, State of Pennsylvania, have invented a new and useful Eleotric Heating and Lighting Apparatus, of

which the following 1s a specification.

Our invention relates to an electric heating and lighting apparatus, the same consisting of a casing having therein an electric lamp or a plurality of electric lamps, means for energizing said lamp or lamps, said casing being adapted to be placed in various positions and providedwith appurtenances whereby it may be coupled with another similarly equipped casing or a number of similarly equipped casings so as to produce combinations of casings according, to requirements of use of the device. The invention is satisfactorilyv illustrated, in the accompanying drawing, but the importantinstrumentalities thereof may be varied, and and so it is to be understood that the invention is not limited to the specific details shown and described, as long as they are within the spirit or scope of the claims.

Figure 1 represents a perspective view of an electric heating and lighting apparatus embodying our invention.

I I Fig. 2 represents a rear view of a portion thereof.

Fig.- 3 represents a horizontal section of a portion on line 2-2 Fig. 2.

Fig. 4 represents a side elevation of one of different combinations th'at may be produced by pluralities of the device.

Fig. 8 is an enlarged detail elevation of one of the casings. I

Other combinations may be formed some of which are shown in an application for Letters Patent filed by us on the fifth da of March, 1918, Serial No. 220,422. y

In thepresent case, similar numerals of reference indicate corresponding parts in theseveral figures. I

Referring to the drawings,

1 designates a casing formed of metal or other suitable material which is closed on its sides, ends and back, and open at what may be termed its front or other part according to the position in which the casing may be placed.

Within said casing is the chamber 2' in which are contained the electric lamps 3 which are properly sustained in said chamher, the heat and light of said lamps being adapted to be deflected outwardly from said chamber to a place of service.

1 designates legs which are connected with the casing by the double ratcheted knuckles 5, the members 6 of which are secured respectively to the ear 7 which is attached to the casing and to the collar 8 to which said leg is attached, and other members -9 of said knuckles are engaged with said members 6, the teeth of said members 9 and 6 being adapted to interlock, each pair of members 9 being connected by screws 10 which are passed through the contiguous members of the knuckles so as to hold the latter in their adjusted and interlocked positions, it being evident that the legs may be placed truly perpendicular or inclined, as shown in Fig. 6, so as to set a casing truly horizontal or inclined and support it in such position according as it may be necessary to place the casing for use.

The legs 4 in their primary condition may be lengthened for which purpose extension pieces 11 may be connectedwith the collars 8, and by means of knuckles 11 attached to said legs 4, see Fig. 4. In some instances, it may be important to sustain a casing whereby it may be turned so as to place it in perpendicular, horizontal or inclined positions, for whichpurpose there is connected with the back of the casing the swivel piece 12whose members are joined by the pivotal bolt 13 which allows the inner member of said piece and consequently the casing to turn on the outer member of said piece, the latter named member being tubular or of the form of a collar which movably receives the standard 14 so that the casing may be raised and lowered and so set at an adjusted height in which latter position it is held by the screw 15 which is fitted to said collar and adapted to tighten against said standard, the efiect of which is evident, see Figs. 2 and 3.

In order to secure the swivel piece firmly to the casing the inner member thereof is attached to the cross braces 16 which are placed on the back of the casing and screwed or otherwise fastened thereto.

The casing will be providedwith connections 17 for the primary electrical conductors 18, whereby the lamps may be energized, and auxiliary connection 19 for ad ditional connections 20, whereby the lamps of additional similarly equipped casings may be energized as shown in Fig. 6, in which latter a plurality of casings are employed side by side to form a combination of casings for purposes requiring a lengthened device. The end casings are supported on the legs 4 and the, intermediate casing has the legs removed therefrom, but the several casings are provided with couplings 21, each of which is formed of the segmental shaped orcurved latch 22 which is connected with the end of a casingand adapted to enter the keeper 23 which is secured to the end of the adjacent casing, said keeper having fitted thereon the screw 24 which is adapted to tighten against the latch, it being evident that sets of casings may be coupled when in a horizontal position, as in Fig. 6, in a vertical position as in Fig. 9, or partly horizontal and partly inclined as in Figs. 5 and 7 the several figures showing various forms of combinations for purposes requiring the same.

In Fig. 8 we show a single casing in inclined position, it being supported at one end on the legs 4: and at the other endon the floor of an apartment, the'legs at said other end having been omitted or removed, while a latch 22 is attached so that another casing may be coupled if so desired.

The standard 14cis provided with suitable feet 25 forming a base, the same preventing overturning of the device. a

It will be seen that the heat and light from the lamps may be used for therapeutic purposes of baking an afflicted part of a human body by subjecting the same to the light and heat, and the apparatus will be found beneficial for various treatments in hospitals and san tariums by physicians, nurses and attendants, or for personal use.

Again the apparatus is serviceable for light alone, or for heat alone, or for bothheat and light, and'it may be employed for drying fruits, vegetables, and other materials and objects, for heating and warming food and other purposes generally, and so to its use we do not limit ourselves. .i

The casing may be removed from the standard and uncoupled from its neighbor, the legs being folded on the sides of the former, and the main electric conductor and auxiliary electric conductors removed from the casing or casings so that a casing or all of the casings; may be readily handled, packed, for transportation, storing, etc., and afterward have the various appurtenances reassembled, placed in operative position when a casing is ready for use either by itself or in connection with other casings, each casing being a unity apparatus of itself.

Owing to the knuckles 11 which couple or connect the extension legs 11 with the main legs 4, and said extension legs being connected with the casing by the knuckles 5, said extension and main legs may be placed in various angular positions so as to set the casing truly upright, inclined or tilted according to the requirements of the device. e

Having thus described our invention what we claim as new and desire to secure by Letters Patent, is Y 1. A member, means on said member for the connection therewith of an electric conductor, a standard, a collar, a pivotal connection for said collar with said member, said member being adapted to be fitted movably on said standard whereby the. member may be adjusted in vertical direction on said standard and turned on the latter, said member having on its back secured thereto braces with which said connectionof the collar and member are connected. 7 2. A support the same comprising a leg, double ratcheted knuckles connecting the leg with a member, an extension piece for the leg, and ratcheted knuckle connections between the leg and each extension piece.

3. A support the same comprising a leg, double ratcheted knuckles connecting the leg with a member, anextension piece for the leg, ratcheted knuckle connections between the leg and each extension piece, and means for adjusting said knuckles to permit the leg and its extension to extend at any desired angle with relation to the member and to each other.
